Re: PAG-oiled components in former mineral oil systems. Corrosion Issues?

1) Residual R-12 is undesirable in A/C systems which have been retrofitted to R-134a and is evidenced by copper plating on steel parts and degraded oil. R-12 is miscible/absorbed into mineral oil and is only removed by lengthy deep vacuum or long atmosphere exposure. 2) Ester based oil was a better ...

Re: Two Condensers connected in series

Measured the air 6" off the asphalt in LV at 165F. OEMs often use belly pans these days to stop recirculated idle air. Bohica's PP experience for severe rare air and temp paramaters w/ turbo would be worth considering. So you are attempting 20 psi boost w/o a charge air cooler (CAC). Somewhat c...

You said lower ram air is for the radiator which leaves upper ram air for CAC and then Radiator. But not enough height for condensers w/o ...

Re: Two Condensers connected in series

This is not about the surface area of the condensers, but of the refrigerant tube internal restriction, e. g., for a 3/8" tube fabbed condenser: entry could be 2 parallel 3/8" tubes throughout. The second condenser could be 2 parallel tubes entry and half way a transition to a single 3/8&q...
